Vitamin D3, K2 and A
Why we need the sun vitamin year-round and which combination is essential.
We can actually form vitamin D3 ourselves. Nonetheless, many people suffer from a vitamin D3 deficiency. Here we will tell you what you can do about this and why the combination of vitamin D3, K2 and A is so important.
Vitamin D3 is vital for us. Unlike other vitamins, we can form the vitamin ourselves with the help of sunlight when it directly hits our skin and the vitamin is also found in some foods.
However, these quantities are extremely small, which is why sunlight is the most important source for the formation of vitamin D3.
Yet many people get too little vitamin D3, not only in winter but also in summer, and for this reason, it can be useful to take a vitamin D3 product.
Vitamin D3 deficiency
Why we absorb too
little vitamin D3
The body is able to store vitamin D3 for a long time, yet many people, especially those living in northern latitudes, suffer from a vitamin D3 deficiency. Symptoms of a deficiency occur in particular during the cold months when we cover our skin with long clothing and the lower angle of the sun’s rays means they are not as intense as they are in summer.
Did you know that many people also suffer from vitamin D3 deficiency in the summer? This is because we protect our skin with sun cream and are more seldom exposed to the sun because of the risk of skin cancer.
In addition, many of us spend our days in enclosed spaces and thus get hardly any or far too little vitamin D3. The fact that more and more people avoid eating fish (vegetarians, vegans) can additionally contribute to a vitamin D3 deficiency.
How to avoid a
vitamin D deficiency
To prevent a vitamin D deficiency, you should ideally spend time in the sun
• at midday (when it’s sunny out)
• without sun cream
• in short clothing (in the summer)
• without a hat or gloves (in the winter).
The daily consumption of fish can also help increase the vitamin D3 level.
Another option for increasing vitamin D3 intake is to take a high-quality nutritional supplement. This can be useful not only in the winter but also in the summer if you, for example, frequently spend time indoors and cannot take advantage of the midday sun due to work.
Why the combination of vitamin D3, K2 and A is particularly effective
Since the metabolic processes in the human organism overlap with one another and are very complex, it may be advisable to take an active substance combination of vitamin D3, K2 and vitamin A to improve the uptake of the sun vitamin with the aid of synergistic cofactors. See for yourself which effects are attributed to vitamins K2 and A.
Effect of vitamin A:
• is important for the healthy function of the immune system
• contributes to healthy iron metabolism
• helps maintain healthy skin and mucous membranes
• plays a role in maintaining healthy vision
Effect of vitamin K:
• supports the maintenance of healthy bones
• is important for healthy blood coagulation
Vitamin D3, K2 and vitamin A should be combined due to the fact that vitamins D3, K2 and A have diverse functions in the human organism. There is an even balance between them and they mutually complement and regulate each other. An adequate supply of all three vitamins is important, particularly for healthy calcium metabolism.
Vitamin D3 initially ensures that calcium is absorbed in the gut from food. In order for the important mineral to get where it is needed, it relies on two important proteins: osteocalcin regulates the incorporation of calcium in bones and teeth, while the matrix Gla protein (MGP) transports excess calcium from the blood vessels and other soft tissues and prevents accumulation there.
Both proteins are adequately synthesised only with the help of vitamin D3 and vitamin A, however they are initially inactive. Only vitamin K2 switches them into their active (carboxylated) form in which they can bind and deposit calcium.
To improve the effect of vitamin D3, vitamin K2 should preferably be in the easily available form MK7 (all-trans), such as it is found, for example, in the vitamin D3 drops from TISSO. Vitamin D3 drops from TISSO additionally have the above-mentioned active substance combination of D3, K2 and vitamin A to incorporate the synergistic cofactors required for vitamin D3.
Vitamin D3 dosage:
How much do I need every day?
Since you can
• produce the sun vitamin with the aid of sunlight,
• absorb it via diet and a nutritional supplement, and
• obtain it from the body’s own stores
the daily requirement is very difficult to determine. According to the German Nutrition Society (DGE), adults are recommended to take about 800 IU vitamin D3, which corresponds to a quantity of about 20 µg per day.

Vitamin D3 ‒ Profile
What is Vitamin D3?
Vitamin D3 is a fat-soluble vitamin that we can obtain only in small quantities from food (ideally in combination with fat). We synthesise the majority ourselves. All we need in order to do this is sunlight, which should hit our skin as unobstructed as possible in order to trigger the formation of vitamin D3.
If sunlight is scarce – this is especially the case in winter – vitamin D production also falls by the wayside which can lead to a vitamin D deficiency over the long term. This deficit can under certain circumstances lead to health problems because the sun vitamin is involved in many metabolic processes.
Vitamin D3 vs. vitamin D2:
what is the difference?
Vitamin D3 is generally referred to as vitamin D, however the vitamin fundamentally exists as vitamin D3 and D2.
Vitamin D3 (cholecalciferol) is one of the most effective forms which is produced by humans themselves through the effect of sunlight. Vitamin D3 is also found in some animal-based foods.
Vitamin D2 (ergocalciferol) is primarily found in plant-based foods. In contrast to vitamin D3, vitamin D2 is less effective since the body cannot properly utilise it.
Vitamin D3 ‒ Food
Vitamin D3 is primarily found in animal-based foods. One of the best food sources is fatty fish whose proportion of vitamin D3 is by no means as high as the proportion of D3 that your body can produce with the aid of sunlight. Below we show you some of the best foods which are rich in vitamin D3.
• Eel (smoked): 3,600 IU (90 µg) per 100 g
• Kipper: 1,200 IU (30 µg) per 100 g
• Herring: 1,000 IU (25 µg) per 100 g
• Eel: 800 IU (20 µg) per 100 g
• Salmon: 640 IU (16 µg) per 100 g
Cod liver oil, with 12,000 IU (300 µg) per 100 g, indeed has a large amount of vitamin D3, however this food is hardly ever on the menu.
How much vitamin D3 can I form myself?
As you already know, vitamin D formation via sunlight is far better than vitamin D intake via food. The sun, or more precisely its UV-B rays, is thus the most important source of vitamin D.
In less than an hour, we can form between 10.000 and 20.000 IU. In order for the light (with a wavelength of 290 to 315 nanometres) to penetrate the upper layers of skin, you should be outdoors between 11 a.m. and 3 p.m., preferably unprotected, when the sun is at its highest and the sunlight is most intense. However, the skin’s individual natural protection should not be exceeded.
Based on the fact that we form far more vitamin D3 in a short time than we can consume from our diet, the sunlight also has a much longer lasting effect than foods enriched with vitamin D3. Through the amount of vitamin D3 which you form from sunlight, the vitamin D level also remains elevated over a longer period of time.
Which factors determine vitamin D3 absorption?
We can absorb significantly more vitamin D3 with the aid of the sun than through food, however the vitamin D level depends on many different factors, such as:
• Skin type (the greater the pigmentation, the less UV radiation penetrates the skin)
• Age (vitamin D production decreases with age)
• Use of sun protection products
• Size of the area of skin exposed to the sun
• Time of day and year
How much vitamin D3 we actually absorb primarily depends on the time of day as well as on the latitude. For an optimal vitamin D3 supply, we should be outdoors between 11 a.m. and 3 p.m. when the sun is at its highest and the UV radiation which is effective for the skin reaches its full intensity. Provided, of course, that the sky is clear.
Once the angle of the sun’s rays is less than 45 degrees – this is especially the case in winter and in northern latitudes – no adequate vitamin D production takes place any longer.
Vitamin D is a nutrient which, on the one hand, we absorb from food and on the other hand, we can form ourselves, however many people in northern latitudes suffer from a vitamin D deficiency. The fault lies with the lack of sunlight and the fact that they mainly spend time in enclosed spaces and eat little to no fish. In this regard, vitamin D3 drops from TISSO offer an oil-based active substance combination of vitamin D3, K2 and A, to increase the vitamin supply and prevent symptoms of deficiency.
